As far as home and car audio, what’s best as to tweeter construction??

As far as car audio, you have your choice of: silk or soft dome tweeters (my preference), aluminum tweeters (a bit harsh to me), plastic tweeters (yuck!), and sometimes, beryllium tweeters. Do you have a preference? Do you have a manufacturer preference? I love: Focal car audio speakers, JBL, and a few Alpine speakers for the car.   For home, I love the Bowers and Wilkins Diamond tweeters in there large bookshelf sized speakers. Cannot afford their Diamond tweeter floor standing speakers, wish I could!! As well as their hi-end headphones, and my Gen-2 Bowers and Wilkins Zeppelin iPod system. Sounds SO good! Bypasses the iPod DAC, and uses their own 96 KHz DAC’s. Better than the B and O iPod speaker system. I tried both before buying the B&W Zeppelin. Does anyone but me use iPods anymore? It also streams Bluetooth, but sounds better to me with my 160 gig iPod with lost-less music files playing on it. Just curious. Maybe I should move this to “vintage”, as very few have/own iPods anymore. 😢. IDK. Just wondering what you guys thought. I was also SHOCKED to hear Neil Pert of RUSH had passed away!! Just heard about this this weekend!! Had NO idea!! One of my two top drummers!! Him and BONZO from Led Zeppelin. So sad. Along with Eddie Van Halen passing this year, they will be sorely missed. Damn……
